The ex-situ catalytic cracking of camelina oil using nickel loaded MCM-41 as catalyst at 450 °C in fixed bed reactor was studied. Results revealed that the yield, selectivity and chemical composition of the liquid products was improved by nickel loaded MCM-41 without affecting
the crystalline structure of MCM-41. Moreover, the loaded nickel onto MCM-41 facilitated the cyclization, alkylation, aromatization, deoxygenation, isomerization and cracking reactions.

1-Butyl-3-methylimidazolium hydrogen sulfate ([Bmim][HSO 4 ]) is utilized to catalyze transesterification of camelina oil with methanol. The major compositions of camelina biodiesel are saturated fatty acid esters (C16:0, C18:0), monounsaturated, and polyunsaturated fatty acid esters (C18:2, C18:3). The effects of reaction temperature, reaction time, M methanol : M Camelina oil , and M [Bmim][HSO4] : M Camelina oil on biodiesel production are investigated in detail, and a general mathematical model is developed to well predict the biodiesel yield. Also, [Bmim][HSO 4 ] is thermally stable to recycle for four times with a high biodiesel yield. The fuel properties of camelina biodiesel are all comparable to the American Society for Testing Materials (ASTM) standards.
Hyperglycemia provides a favorable breeding ground for bacteria, resulting in repeated and persistent inflammation of wounds and prolonged healing processes. In this study, platinum (Pt) nanoparticles (NPs) and glucose oxidase (GOx) were decorated on the surface of camelina lipid droplets (OB) linked with hFGF2, forming PGOB through in situ reduction of Pt ions and electrostatic adsorption, respectively. PGOB exhibits cascade enzyme catalytic activity, which can be activated by glucose in diabetic wound tissues. Specifically, GOx on PGOB catalyzes glucose into hydrogen peroxide, which can further decompose into hydroxyl radicals that have higher toxicity for bacterial inactivation. Additionally, glucose decomposition creates a low pH microenvironment, facilitating the cascade catalytic activity that ensures better bacterial suppression within the wound tissues. Furthermore, hFGF2 promotes the proliferation and migration of fibroblasts. Both in vitro and in vivo experiments confirm that PGOB effectively accelerates wound healing processes through bacteria inactivation and tissue regeneration. This study has developed an alternative strategy for glucose-triggered synergistic cascade therapy for diabetic wounds.
